How many years have people speculated about p2w in WoW by now? Hm, when was That Retarded Horse™ released...
There won't be any time when Blizzard directly sells something that directly, right then, makes your character stronger.
I think people should check some actual P2W games (usually undeservedly popular flash/iOS/Android games) to see the extent P2W can go.
Right now we have people arguing that buying charms is p2w, their logic eludes me.
I'll gladly pay for +100% experience though. I like to level as fast as I can. Sue me.
